Silicone sealer is a red herring and not the reason for failures, this video continues to spread misinformation regarding the GR86/BRZ.

As long as a temperatures and oil levels are kept in close check with a proper oil pan/baffle/viscosity and cooler setup, these engines can survive reliably and that has been seen with the GR cup cars if you read closely about the engine "failures" they have had on track.
I 100% agree with this… I have been doing lots of research and spoke to the owner at “The86shop” in QLD Australian. He has raced 86's for over ten years and is very knowledgeable on the platform. He recommends running a Motul 8100 power 0w20 with an oil cooler and doesn’t run a oil sump baffle as production racing series doesn’t let you. He has done multiple Bathurst 6 hour races on both his and other customers 86’s plus other race meetings and has never had an engine failure which I found extremely interesting as everyone says you need to run “thicker oil” and a sump baffle.

This is an inherent design flaw with flat engines, isn't even subaru specific, this is exactly why porsches use dry sump ($$$). bigger displacement over gen1 means that oil is getting trapped in the timing cover causing a pressure drop on high G right hand turns, conditions you're only ever seeing on a track fortunately. the excessive RTV is beat to death at this point and as far as I know there are zero confirmed cases of engines being blown by excessive RTV. Subaru redesigned the pickup to have 5 sides, and says apparently there isn't enough RTV to clog the pickup. Even if that's totally true, the jelly seen in your pan is concerning. the oil pressure issues have been pretty well documented by 900brz. it's momentary, but after it happens enough times the engine could go at any point, like yours. seems like you need to upgrade the oiling system if you want to reliably track these things, which is a shame with how they market them. I don't track mine so it doesn't bother me but I'll likely have the pan dropped, inspected, and replaced with the correct amount of RTV as soon as the warranty is up.

@@MrAchilles113 no, the silicone is not the issue and this had been known for a long time now in the gen2 community. the issue is the oil pan / oil pickup design when going thru a hard right hand turn. the car loses oil pressure. you can get an accusump wich is a canister that hold pressurized oil and delivers it when the engine oil pressure drops. it is much cheaper than a new engine or a dry sump. it would probably prevent the majority of oil pressure related failures

@@tone3560 right. I'm not saying the silicon is the culprit, just confirming that they do use a copious amount of silicone. I know they suffer from oil starvation under extreme loads.
Its not about RTV in FA24 its about oil not going back to sump and pump has nothing to pick cuz oil stays in heads bigger sump can help ,problem for Misha here is that this happened on slow drive with no hard G corners and that is very hard to explain how engine can blow it self in this situation why engine had no oil pressure at 80kmh on strait road on drive to gas station.
Maybe sludge was pickup up hot on track, cools near the pump when parked and when it warms up again a it comes loose as a clump and clogs the pump or gallery, starves the engine.
Per ChatGPT “Silicone RTV (Room Temperature Vulcanizing) does not melt after it has fully cured. Once cured, silicone RTV can withstand high temperatures, typically ranging from 400°F to 600°F (204°C to 315°C) depending on the specific product. Instead of melting, silicone will eventually degrade or harden when exposed to temperatures beyond its rated limits, but it won’t revert to a liquid state like some other materials might.” 4:19
what happens if you through cured RTV in a blender with oil? Is it possible pieces broke off and were shredded throughout the engine until creating that paste?
right, i dont get how these youtube channels keep pushing this nonsense... its totally click bait because they didnt do their due diligence, and then blame subaru.
@@nastasiaj yes, RTV is not the issue. the car drops oil pressure on hard right hand turns. if people just got some type of accusump it would prevent 90% of engine failure instead of playing the lottery-
I've seen that jelly/sludge cause a failure on a new built engine. They over packed the oil pump with assembly grease to help build oil pressure on first start, drove 50 miles did an oil change, drove 200 miles did an oil change drove 500 miles did an oil change every time the filter was cut open and inspected an was clean. 1000 miles in rod knock started they pulled the pan and it was exactly like that slimey grey goo in the bottom.
@@TML34 testing has been done that there arent really any downsides for the fa24 and it REALLY helps oil pressure loss which is the main killer of these engines.

RTV is not the issue... it is right hand turns. and there is an easy fix too, people just like playing the lottery instead of spending a few hundred bucks on an accusump
Seems that 2nd gen GR86/BRZ are more susceptible to oil starvation issues in general. And not just due clodgs of excess sealant. FA24 more pleasant engine for daily drive, but for track use with high long side-Gs, old FA20 seems more resilant
All subaru engines are subject to oil starvation... there is so many videos on how to fix these issues.. the best being on MOTOIQ... people just refuse to educate them selves and think they can fix anything.. Subaru engines are finicky, but when done correctly can be very very reliable, even at high HP.. The FA24 in the wrx holds upwards of 500hp on stock components, with just bolt ons and e85.. the issues are the same that have always plagued these engines, track use without proper setup.. a pick up/baffle etc have to be used.. the cases puke oil, and its well documented..
@@juanticimoits no excuse though, Subaru have known about these issues for 30+ years and not fixed them. IMO there is no way to fix these issues without an Accusump or Drysump. Baffles do not work in the EJ, the oil capacity is just wayyyy too low. The EJ needs like a 8 litre sump, not 4.4. 4.4 litres is enough for a 1.4 or 1.3 engine , not a 2.0 turbo.
all you need is an accusump. people jsut dont want to spend the 400 something bucks to get one. what a shame that such a simple thing could save 90% of the engine failure on gen2 cars
@@bigkaswrx8115 obviously. but shit happens and every engine nad every car has flaws. the oil pan is just bad. unless someone makes a completely new oil pan that eliminates the oil completely sloshing out of the oil pan and away from the pickup, an accusump will be you best option. just get the biggest one you can I guess :D
They still haven't solved the oil starvation issues...smh. I've always wanted a brz/gr-86 for the platform but this a big turn off. I would have much preferred a version of the M20a or A25 toyota engine. Inline is generally just proven and reliable.
Those two engines are Atkinson cycle engines specifically designed for efficiency and emissions only and are meant to be ideally paired with hybrid systems. In non-hybrid cars with those two engines, they are completely gutless. As for the starvation, the aftermarket will find solutions with time and research and as soon as people stop thinking silicone sealer is a problem.
@@antoinedoinell its a shame as the issue has been known since 1990's.... subaru have done nothing to stop it. They should have at least made the performance cars woth baffled sumps !

I still don't understand why you didn't upgrade at first place engine if you are know you will be tracking that car, as minimum upgrade oil pan with baffled sump and oil pick up which would prevent that issue for time being
I believe it's because he did not expect that, or conspiracy theory he did that for the content haha. Also apparently he tried to seal it better than subaru did
@@alphaenterprise2232 I wouldn't expect that too, but I assume he built it as track car? If yes then I would build at least forged engine for track car with 11mm or 14mm headstuds just in case Baffled sump and oil pick up is literally minimum upgrade for that car, if he does more drifting or he exceeds that then dry sump it to be on safe side, over here in UK people run on their EJ207 or EJ257 baffled sump with uprated oil pick up and they do a lot of sprint series and track days without any issues, dry sump is if you are loaded Hopefully won't end up as Donut media and their Subaru High and low car builds🤦
Problem is, the quality of gaskets and sealing rings is going downhill at the moment, even for OEM parts. So they are sort of promoting siliconing up things to cover for the crappy gasket's you are getting. And as another TH-camr said, this is what will kill the internal combustion engine... Crappy unreliable parts, even when you pay good money for it.
I had a '99 2.5 Legacy back in the day. Great car, loved the handling etc. One day, as I was pulling up to the house, the engine just stopped dead and wouldn't turn over. Crank seized. :(
These cars loose a lot of oil pressure during sustained and harsh right handed turns. From what I’ve seen from people who race them, an oil sump, the right oil (a 40 weight oil for racing), a baffled oil pan, and adding an extra .5 qt of oil will reduce the amount of pressure loss significantly.
We run 2 stock GR86's at the NurburgRing during tourist weekends. They are also used as daily drivers. No issues yet, but we don't drive as fast, or do as many laps as Misha. I was waiting to see what the failure was as we are considering changing cars next year. Its disappointing to have to worry about possible engine failure.
@@saitabit baffle plate is not a big partitioned crankcase (what it should have had, but not yet in production) 😉. 🤔I don't remember the grade of the oil, but he was switching to a slightly higher grade, to try not to have this problem... he talked about it on his videos
I highly recomend looking into an accusump system, it delivers oil when whe oil pressure drops to save the engine from failure. the cars lose oil pressure on right hand turns. it is not that expensive either.
why i got a built engine in my subaru was because my engine blew up leaving a gas station parking lot at 15 mph. lol no high revving or launching honestly i shouldnt have gotten an IAG engine and rebuilt it but i did. the same issue is inevitably going to happen again.
I have no idea why people track the cars knowing there is an issue, and that there is a clear and simple way to fix it. get a fucking accusump. fuck the oil baffles, fuck scraping off the RTV just get an accusump. cheap and easy to install too
@@turbo________ a few people have data logged a bunch of runs on the track and even with accusump on long right turns, the engine oil pressure drops... and thats with bigger pan and baffles too. I wonder how porsche does it at this point lol
@@NimaSomeh yea I have seen that. still it is the best you can do right now. A bigger canister would help or maybe a dual canister setup so the 2 individually smaller canisters fit under the hood. porsche uses some kind of a dry sump system from what I know
My first gen engine also died on the street just by idling in the parking lot. Very strange stuff. So it’s something that affects both gens. Curious if they will continue the way with the gr yaris engine in the next gens as they already racing a gr86 on altenative fuel with that engine.
Stroker kits aren't really about peak power but more torque... so although number gains won't be much you could make 100hp like 2000rpm lower maybe but peak power lower
@@arielatom300heps It's better to run this car without an oil cooler. An oil cooler adds extra lines for the oil and further reduces pressure. Only thing you can do is run a thicker oil like 5W-30 or 40 that sees less viscosity at high temps.
Here it would be worth thinking about building a new car . This engine is...The problems were mentioned several times in the chat . I would really try maybe a different car / engine . How about taking this as a project and doing some swapping ?
Wait until you guys find out the pistons on the HKS pistons are the exact bore as OEM so you can’t bore out the cylinder walls in the event of damages, you have to use oem new cylinder walls or pray yours don’t have damage.

You know some other cheap sports cars at the same price of the GR86 *not* known for engine failures? Mazda Miata MX-5, VW Golf GTI, Honda Civic Si. Being cheap isn't the issue, it has a design flaw.
notorious? you mean the people that know that there is an issue on track with right hand turns, are given a way to prevent it and still choose to play the lottery? just get a fucking accusump it is not expensive or hard to install
they are killing it off, because it doesnt sell. its also due to safety regulations in EU, but videos like this, are also part of the reason why sales are down.. tracking a stock fa24 without a pan,pickup,baffle combo is asking for starvation issues. its all over motoiqs page.. they explain it in detail..
@@juanticimo It sells well enough. I think around 300,000 units between the two generations. I think Subaru isn't particularly committed to the car and Toyota is looking to move sportscar dev in house, replacing this with a new Celica with a new 2.0T.
Holy shit! The RTV issue isn't just specific to the oil pan, it extends to the entire engine assembly? That's it, my last 3 new vehicles were Subaru's.. next one won't be.
Seems like most folks are overfilling by .5 or 1 qt and are fine.. Granted they're not on the Ring, but just 'regular' tracks.. If you're really concerned.. should've gotten an Accusump.. maintains pressure in the oil system no matter what.. $800 USD
Normal amount of sealant from factory not the cause of failure... maybe oil starvation due to oil surge on track running Check the oil pump in the front cover.... How are the cams and cam caps
There’s an overload of RTV everywhere in the engine from the factory, not just the oil pan. Plus, the engine doesn’t maintain oil pressure around right hand corners. It’s just a terribly designed engine, as most Subaru engines are. Toyota should be building their owns engines with the massive resources that they have
I had a deposit down for a new GR86 when they came out but ended up getting a S2000 ap1 instead. Best decision I ever made but it’s not a daily for me so decision was easier!
Damn, and this engine is never bin taken apart? That amount of silicone is just terrible! I can imagine the sludge/jelly was going true the oil channels, and when engine was cooling down it blocks the flow. And when you drove it a few miles the bearings give up. Great of you guys building the car again, more reliable as ever. The new owner will have the most fun! And jokes aside, first thing in my head was siliconector joke!
I am done with the FRS, BRZ, 86 line up. There has never been a good experice for me owning a last gen and even now a new gen with the ove rusage of RTV. I hope Subaru and Toyota learn from this because in my mind it is damaging my experince with both companies and I know of others that feel the same way.
Seems like the common issue with sealant. Thank you for rebuilding the engine in such a high spec guys👏🏻 big respect for that. Can’t wait to pick it up!🥰
RTV is not the issue. right hand turns are. just get an accusump, it is around 400 euro and it delivers oil to the engine when it drop oil pressure, it is easy to install and it would prevent 90% of engine failure on the FA24.
So ... did it fail because exczessive silicone blocked the oil passages and caused the bearing failure... or is it bearing failure because ... subaru ? :D
For it to work properly, you need to use the block to pin the sleeve or completely close the cylinder sleeve. There are companies in Poland that handle this.
Okay… doesn‘t really sound great since I got myself a GR86 a month ago. So what would you recommend doing about this RTV/Oil problem in general? I mean the car still has warranty so just drive it till it dies and let Toyota repair it then?
Look up the issue online. Lots of forum entries and discussions about it. Most people recommend filling in more oil and maybe thicker heavier oil. Mods like the sump baffle will only benefit on track. Sealant blocking the oil pickup is not the main issue and will only affect the engine sometime later as it takes time for the sealant to go loose and find it's way into problem areas.
man there is so much misinformation in this entire comment section.... the oil was ran low. misha had a visible low oil light on before engine failure. keep an eye on your oil level and this will never happen to you, it had nothing to do with the RTV/silicon, that "jelly" was created by misha running ravaged overheated oil low, to the point of destruction. Also, there was an aftermarket baffle plate in there, meaning someone opened that engine and re-applied silicon to it, meaning THEY laid that excess silicon in there.
Go with 5W-20. If you track the car or autocross, change the oil. Run a half quart overfill. Only use at least 5W-20. Don't use 0W-20. The owner's manual has both 0W-20 and 5W-20. Watch the temperature. If it gets above 240 degrees Fahrenheit, then go with 5W-30. The Subaru's owner manual has 5W-30 as well. There's nothing you can/should do at the moment. The issue is correlated with track driving. If you don't track the car, Do nothing besides run 5W-20.
@@avery4528 suabaru has always used alot of sealant when joining the engine components, but we cannot be sure of how much of that silicon actually broke free. regardless, the engine failure was not from silicon plugging anything, he ran the engine low on oil. there hasnt been a single engine failure concretely proven to be caused by RTV.
Misha what oil were you running when this happened? 0W20? 0W30? or 5W30? Also how often did you change the oil? And how many kilometres was on your GR86 when this happened? I would love to hear a response from you... Thanks!
Misha, I strongly recommend looking into what 900brz and Drivers Paddock on TH-cam have posted about this issue. The RTV is not the main issue as a quick dirty fix at the moment is an oil overfill and syms baffle. Oil cooler is a double edged sword as it keeps oil temps from getting into a danger zone but will be another part that will prevent oil from returning to the pan/sump.
900BRZ showed syms baffle doesn't work. He's had success with a prototype larger oil pan by verus engineering that is still early in the production process.
I always took my GT86 then BRZ to main dealer and this is the very reason my Gr86 will be going to the dealer for servicing to keep the 10 year warranty
Porsche has had TONS of its own issues with their boxer engines as well. Boxer engines are wonderful for low CG but a much more complex motor to build due to the layout. Subaru does a fine job for their non-performance oriented motors but when stressed in performance applications, Subaru seems to run out of talent.
Your on the money with that root cause, way to much silicone used in that reassembly for sure hope it go well from now all the best use Loctite Gasket Sealant very good for Subaru engines Re:
known fault that the gaskets on the head were too thickly applied with silicon - breaks off in the engine - drops to sump - blocks sump pick up starves engine and boom... Toyota i thought had a recall for this ?

@@MrAchilles113 no, the silicone is not the issue and this had been known for a long time now in the gen2 community. the issue is the oil pan / oil pickup design when going thru a hard right hand turn. the car loses oil pressure. you can get an accusump wich is a canister that hold pressurized oil and delivers it when the engine oil pressure drops. it is much cheaper than a new engine or a dry sump. it would probably prevent the majority of oil pressure related failures

rtv silicon is just a catalyst....it is right hand high G turns
@@tone3560 right. I'm not saying the silicon is the culprit, just confirming that they do use a copious amount of silicone. I know they suffer from oil starvation under extreme loads.
Its not about RTV in FA24 its about oil not going back to sump and pump has nothing to pick cuz oil stays in heads bigger sump can help ,problem for Misha here is that this happened on slow drive with no hard G corners and that is very hard to explain how engine can blow it self in this situation why engine had no oil pressure at 80kmh on strait road on drive to gas station.
its doest not break in second. It happens slowly.
@@jagymeister well he was on track so yea something might happend there but he didnt noticed and it started getting worse and worse with time
@@wildfrog5803 He had a few recorded money shifts with the car so people are speculating that could have been the cause.
Maybe sludge was pickup up hot on track, cools near the pump when parked and when it warms up again a it comes loose as a clump and clogs the pump or gallery, starves the engine.
@@EmptyJarDoto lol.. that might have done it.. over time it could have just failed. but he blames rtv? lol.
Per ChatGPT
“Silicone RTV (Room Temperature Vulcanizing) does not melt after it has fully cured. Once cured, silicone RTV can withstand high temperatures, typically ranging from 400°F to 600°F (204°C to 315°C) depending on the specific product. Instead of melting, silicone will eventually degrade or harden when exposed to temperatures beyond its rated limits, but it won’t revert to a liquid state like some other materials might.” 4:19
what happens if you through cured RTV in a blender with oil? Is it possible pieces broke off and were shredded throughout the engine until creating that paste?
To solve reliability problems, a bulkhead oil pan must be installed. The FA24 engine hates right turns because the oil pressure dropped drastically.
Did you even watch the video?
@@nastasiaj
I do and I agree with him.
We knew the problem well before this engine broke.
Look at the comments, many will tell you the same thing 😉
right, i dont get how these youtube channels keep pushing this nonsense... its totally click bait because they didnt do their due diligence, and then blame subaru.
@@nastasiaj yes, RTV is not the issue. the car drops oil pressure on hard right hand turns. if people just got some type of accusump it would prevent 90% of engine failure instead of playing the lottery-
I've seen that jelly/sludge cause a failure on a new built engine. They over packed the oil pump with assembly grease to help build oil pressure on first start, drove 50 miles did an oil change, drove 200 miles did an oil change drove 500 miles did an oil change every time the filter was cut open and inspected an was clean. 1000 miles in rod knock started they pulled the pan and it was exactly like that slimey grey goo in the bottom.
We have a saying in Australia.... Do your best Silicone the rest.... I guess it's made its way to Japan.....
Проблема не в RTV, а в том, что при правых поворотах с большим G, масло накапливается в левой голове и не попадает в поддон.
FA24 and make sure you overfill the oil by almost a quart.
That’s sketchy. Engines in normal use shouldn’t be overfilled.
@@TML34it's really not overfill. The max line is conservative, it's 1 quart less than real max. 500-750 ml over max line is totally fine.
@@TML34 testing has been done that there arent really any downsides for the fa24 and it REALLY helps oil pressure loss which is the main killer of these engines.
@@TML34 you are worried about foaming, and that doesnt happen till prob double the required amount of oil in the pan. a quart over, hell even 2 quarts over is totally fine.

@@juanticimo always worried about that, sometimes just depends on how the oil pan is designed.
Vulcan (a french youtuber) has broke his GR86 the same way. After a recall, the manufacturer put too much join and end it ends up the same way
RTV is not the issue... it is right hand turns. and there is an easy fix too, people just like playing the lottery instead of spending a few hundred bucks on an accusump
i wouldn''t rebuild a block after a bearing failure. Bearing debris is more difficult to clean out the oil passages fully.
Seems that 2nd gen GR86/BRZ are more susceptible to oil starvation issues in general. And not just due clodgs of excess sealant. FA24 more pleasant engine for daily drive, but for track use with high long side-Gs, old FA20 seems more resilant
All subaru engines are subject to oil starvation... there is so many videos on how to fix these issues.. the best being on MOTOIQ... people just refuse to educate them selves and think they can fix anything.. Subaru engines are finicky, but when done correctly can be very very reliable, even at high HP.. The FA24 in the wrx holds upwards of 500hp on stock components, with just bolt ons and e85.. the issues are the same that have always plagued these engines, track use without proper setup.. a pick up/baffle etc have to be used.. the cases puke oil, and its well documented..
@@juanticimoits no excuse though, Subaru have known about these issues for 30+ years and not fixed them. IMO there is no way to fix these issues without an Accusump or Drysump. Baffles do not work in the EJ, the oil capacity is just wayyyy too low. The EJ needs like a 8 litre sump, not 4.4. 4.4 litres is enough for a 1.4 or 1.3 engine , not a 2.0 turbo.
all you need is an accusump. people jsut dont want to spend the 400 something bucks to get one. what a shame that such a simple thing could save 90% of the engine failure on gen2 cars
@@turbo________ I think the point is you shouldnt have to buy an accusump. And Subarus S**t engineering should have been fixed 30 years ago .
@@bigkaswrx8115 obviously. but shit happens and every engine nad every car has flaws. the oil pan is just bad. unless someone makes a completely new oil pan that eliminates the oil completely sloshing out of the oil pan and away from the pickup, an accusump will be you best option. just get the biggest one you can I guess :D
They still haven't solved the oil starvation issues...smh. I've always wanted a brz/gr-86 for the platform but this a big turn off. I would have much preferred a version of the M20a or A25 toyota engine. Inline is generally just proven and reliable.
Those two engines are Atkinson cycle engines specifically designed for efficiency and emissions only and are meant to be ideally paired with hybrid systems. In non-hybrid cars with those two engines, they are completely gutless. As for the starvation, the aftermarket will find solutions with time and research and as soon as people stop thinking silicone sealer is a problem.
@@saad8029sealant is part of the problem. If you ignore it now it will cost you an engine sometime in the future.
@@antoinedoinell its a shame as the issue has been known since 1990's.... subaru have done nothing to stop it. They should have at least made the performance cars woth baffled sumps !
@@saad8029I know. I said a version of those specific engines. It’s Toyota. History has proven they can build inline 4’s.
You can run a 500ml overfill with 5-30 or 5-40 with oil cooler and avoid most of these problems. Have a look at the testing 900brz is doing.
Boggles my mind why they wouldn't just use a gasket like everyone else. It seems like it would also be quicker to assemble as well.
it is asembled by machines. so RTV is simpler. still RTV is not the issue and this has been known for a while now. it is hard right hand turns on track. there is a simple fix too, just get a fucking accusump instead of playing the lottery
I still don't understand why you didn't upgrade at first place engine if you are know you will be tracking that car, as minimum upgrade oil pan with baffled sump and oil pick up which would prevent that issue for time being
I believe it's because he did not expect that, or conspiracy theory he did that for the content haha. Also apparently he tried to seal it better than subaru did
@@alphaenterprise2232 I wouldn't expect that too, but I assume he built it as track car? If yes then I would build at least forged engine for track car with 11mm or 14mm headstuds just in case
Baffled sump and oil pick up is literally minimum upgrade for that car, if he does more drifting or he exceeds that then dry sump it to be on safe side, over here in UK people run on their EJ207 or EJ257 baffled sump with uprated oil pick up and they do a lot of sprint series and track days without any issues, dry sump is if you are loaded
Hopefully won't end up as Donut media and their Subaru High and low car builds🤦
Problem is, the quality of gaskets and sealing rings is going downhill at the moment, even for OEM parts.
So they are sort of promoting siliconing up things to cover for the crappy gasket's you are getting.
And as another TH-camr said, this is what will kill the internal combustion engine... Crappy unreliable parts, even when you pay good money for it.
That bearing is impressively fucked. I don't even know how much worse it could get before it exploded.
Gr86 common issue... terrible oil handling... you need a dry sump and custom oil pan
I had a '99 2.5 Legacy back in the day. Great car, loved the handling etc. One day, as I was pulling up to the house, the engine just stopped dead and wouldn't turn over. Crank seized. :(
Amazes me how easily Subaru engines fall apart. As someone that had a Ver. 5 STi engine....
These cars loose a lot of oil pressure during sustained and harsh right handed turns. From what I’ve seen from people who race them, an oil sump, the right oil (a 40 weight oil for racing), a baffled oil pan, and adding an extra .5 qt of oil will reduce the amount of pressure loss significantly.
Also removing the heater core helps with reducing the oil pressure loss in these engines
We run 2 stock GR86's at the NurburgRing during tourist weekends. They are also used as daily drivers. No issues yet, but we don't drive as fast, or do as many laps as Misha. I was waiting to see what the failure was as we are considering changing cars next year. Its disappointing to have to worry about possible engine failure.
Install a partitioned crankcase, with suitable oil
@@THESHADOW97139 Misha's 86 had a Cusco baffle plate and it still failed. Would be interested to know what oil he used and how often they changed it.
@@saitabit baffle plate is not a big partitioned crankcase (what it should have had, but not yet in production) 😉.
🤔I don't remember the grade of the oil, but he was switching to a slightly higher grade, to try not to have this problem... he talked about it on his videos
you need a pan, pickup and baffle, and also run about an extra quart, or more to keep the pressure up. otherwise flat engines do flat engine things..
I highly recomend looking into an accusump system, it delivers oil when whe oil pressure drops to save the engine from failure. the cars lose oil pressure on right hand turns. it is not that expensive either.
There is a reason why inline four is used by everybody. Like that meme: just because you are different does not mean u are useful
Ah, yes. The good ol' Subaru banana crank.
Lol 😀
make sure to inspect every oil galley before reassembly
Hrm. Oil starvation, leading to a spun bearing... On a Subaru... why am I NOT surprised!?
why i got a built engine in my subaru was because my engine blew up leaving a gas station parking lot at 15 mph. lol no high revving or launching honestly i shouldnt have gotten an IAG engine and rebuilt it but i did. the same issue is inevitably going to happen again.
Owner is getting a jewel, built engine with a hks stroker!
misha, those engine have oil starvation issues under high G's. unless you address that, it going to blow up again. good luck !
I have no idea why people track the cars knowing there is an issue, and that there is a clear and simple way to fix it. get a fucking accusump. fuck the oil baffles, fuck scraping off the RTV just get an accusump. cheap and easy to install too
@@turbo________ a few people have data logged a bunch of runs on the track and even with accusump on long right turns, the engine oil pressure drops... and thats with bigger pan and baffles too. I wonder how porsche does it at this point lol
@@NimaSomeh yea I have seen that. still it is the best you can do right now. A bigger canister would help or maybe a dual canister setup so the 2 individually smaller canisters fit under the hood. porsche uses some kind of a dry sump system from what I know
This is one of the more informative RTV issues videos, damn makes me rethink how long I wanna keep the car
My first gen engine also died on the street just by idling in the parking lot. Very strange stuff. So it’s something that affects both gens. Curious if they will continue the way with the gr yaris engine in the next gens as they already racing a gr86 on altenative fuel with that engine.
Hopefully there is a kit with your stroker kit that has a better baffling system for the oil starvation problem during the right hand turns.
Stroker kits aren't really about peak power but more torque... so although number gains won't be much you could make 100hp like 2000rpm lower maybe but peak power lower
it is mostly about having to replace the internals so why not go with the stronger HKS goodies
@turbo________ I totally agree... if something breaks, perfect time to upgrade
Is this a video from a long time ago ? Or is it only now being rebuild?
Wouldn't a oil analysis showed the amount of silicone in the oil?
Good idea !.
Oil analysts would have been good insurance since the car was being tracked hard without a oil cooler…
So it all boils down to user error, case closed
This should be an old video for all I know
@@arielatom300heps It's better to run this car without an oil cooler. An oil cooler adds extra lines for the oil and further reduces pressure. Only thing you can do is run a thicker oil like 5W-30 or 40 that sees less viscosity at high temps.
Here it would be worth thinking about building a new car . This engine is...The problems were mentioned several times in the chat . I would really try maybe a different car / engine . How about taking this as a project and doing some swapping ?
V8 GR86 would be awesome.
Any updates on the build? Really interested to see how much it makes with the stroker kit!
Wait until you guys find out the pistons on the HKS pistons are the exact bore as OEM so you can’t bore out the cylinder walls in the event of damages, you have to use oem new cylinder walls or pray yours don’t have damage. This is straight from HKS for their specs and IAG as far as potential machining issues lol
Why can't subaru just use gasket instead of RTV? They would always end up on oil pick up and block it. This has been an issue for a long time already.
RTV is not the issue. right hand turns on track are. just get an accusump and it would fix it and prevent engine failure on 90% of FA24s
@@turbo________ it is. Did you watch the video? Check atleast at 4:10 and see the excess rtvs on the oil sump.
@@butcht6309 can you read? I didnt say that there is no excess RTV. I said that the RTV is not the issue.
It's a cheap sportscar notorious for engine failures.
You know some other cheap sports cars at the same price of the GR86 *not* known for engine failures? Mazda Miata MX-5, VW Golf GTI, Honda Civic Si. Being cheap isn't the issue, it has a design flaw.
notorious? you mean the people that know that there is an issue on track with right hand turns, are given a way to prevent it and still choose to play the lottery? just get a fucking accusump it is not expensive or hard to install
@@turbo________ its no use people love to jump to conclusions with these things.
Will be interesting to see how much power the car makes on the dyno once the stroker kit is installed.
I sold my GR86 after discovering the RTV issues almost 2 years ago. Never regretted that wise decision.
Its a known issue that the excess gasket material blocks the oil pickup
This is not the problem here
Probably why toyota is ending their joint venture and i believe they will put the 1.6 turbo from the gr yaris now. Or the newly developed 2 liter
they are killing it off, because it doesnt sell. its also due to safety regulations in EU, but videos like this, are also part of the reason why sales are down.. tracking a stock fa24 without a pan,pickup,baffle combo is asking for starvation issues. its all over motoiqs page.. they explain it in detail..
@@juanticimo It sells well enough. I think around 300,000 units between the two generations. I think Subaru isn't particularly committed to the car and Toyota is looking to move sportscar dev in house, replacing this with a new Celica with a new 2.0T.
I read the 2028 GR86 is supposed to use the three cylinder 300hp engine and be a hybrid.
A larger capacity oil pan with revised baffles should be installed on the new motor...and the new owner should run a heavier weight oil
Holy shit! The RTV issue isn't just specific to the oil pan, it extends to the entire engine assembly? That's it, my last 3 new vehicles were Subaru's.. next one won't be.
Seems like most folks are overfilling by .5 or 1 qt and are fine.. Granted they're not on the Ring, but just 'regular' tracks.. If you're really concerned.. should've gotten an Accusump.. maintains pressure in the oil system no matter what.. $800 USD
Normal amount of sealant from factory not the cause of failure... maybe oil starvation due to oil surge on track running
Check the oil pump in the front cover....
How are the cams and cam caps
Subaru and not getting oil, name a more iconic duo
cant wait for the update to see how this thing sounds and drives with the stroker kit!!
judging by the Cusco plate in the pan, someone opened the engine and overused the sealant during assembly. Subaru has nothing to do with this.
There’s an overload of RTV everywhere in the engine from the factory, not just the oil pan. Plus, the engine doesn’t maintain oil pressure around right hand corners. It’s just a terribly designed engine, as most Subaru engines are. Toyota should be building their owns engines with the massive resources that they have
I had a deposit down for a new GR86 when they came out but ended up getting a S2000 ap1 instead. Best decision I ever made but it’s not a daily for me so decision was easier!
lesson: never let an engine warm up by allowing it to idle
There’s a reason why cars with reliable boxers engines start a 80k and the with the letter P…
Damn, and this engine is never bin taken apart? That amount of silicone is just terrible! I can imagine the sludge/jelly was going true the oil channels, and when engine was cooling down it blocks the flow. And when you drove it a few miles the bearings give up.
Great of you guys building the car again, more reliable as ever. The new owner will have the most fun!
And jokes aside, first thing in my head was siliconector joke!
I am done with the FRS, BRZ, 86 line up. There has never been a good experice for me owning a last gen and even now a new gen with the ove rusage of RTV. I hope Subaru and Toyota learn from this because in my mind it is damaging my experince with both companies and I know of others that feel the same way.
Even in Japan, these GT/GR 86 engines are notorious for being unreliable if you did something to it.
Knock, knock. - Who's there? - The Subaru engine.
Does that have any bearing? (I own a few)
Is it silicon instead of solid gasket? Can you make custom gaskets then? Or is it the O ring type gasket i dunno lol. Goodluck Misha
It’s fine to use RTV-type sealant but you have to be precise with the amount applied.
This is a boxer engine! The problem is not the gasket! It’s a problem between the two blocks and the crankshaft
most engines use RTV and its perfectly fine. Problem is amount of it.
RTV is not the issue, right hand turns are. just get an accusump and it would fix 90% of engine failures on the FA24
Seems like the common issue with sealant.
Thank you for rebuilding the engine in such a high spec guys👏🏻 big respect for that.
Can’t wait to pick it up!🥰
So you are the lucky one
RTV is not the issue. right hand turns are. just get an accusump, it is around 400 euro and it delivers oil to the engine when it drop oil pressure, it is easy to install and it would prevent 90% of engine failure on the FA24.
There is a research on that engine
It looses oil pressure on high speed turns.
So ... did it fail because exczessive silicone blocked the oil passages and caused the bearing failure... or is it bearing failure because ... subaru ? :D
this is partially why i got the mx5RF a bit more robust even though the center of gravity is slightly higher

@@bearclaw5115 I'm aware
For it to work properly, you need to use the block to pin the sleeve or completely close the cylinder sleeve. There are companies in Poland that handle this.
Pin the sleeve?? You mean to block certain oil passages?

Okay… doesn‘t really sound great since I got myself a GR86 a month ago. So what would you recommend doing about this RTV/Oil problem in general? I mean the car still has warranty so just drive it till it dies and let Toyota repair it then?
Look up the issue online. Lots of forum entries and discussions about it. Most people recommend filling in more oil and maybe thicker heavier oil. Mods like the sump baffle will only benefit on track. Sealant blocking the oil pickup is not the main issue and will only affect the engine sometime later as it takes time for the sealant to go loose and find it's way into problem areas.
man there is so much misinformation in this entire comment section.... the oil was ran low. misha had a visible low oil light on before engine failure. keep an eye on your oil level and this will never happen to you, it had nothing to do with the RTV/silicon, that "jelly" was created by misha running ravaged overheated oil low, to the point of destruction. Also, there was an aftermarket baffle plate in there, meaning someone opened that engine and re-applied silicon to it, meaning THEY laid that excess silicon in there.
Go with 5W-20. If you track the car or autocross, change the oil. Run a half quart overfill. Only use at least 5W-20. Don't use 0W-20. The owner's manual has both 0W-20 and 5W-20. Watch the temperature. If it gets above 240 degrees Fahrenheit, then go with 5W-30. The Subaru's owner manual has 5W-30 as well. There's nothing you can/should do at the moment. The issue is correlated with track driving. If you don't track the car, Do nothing besides run 5W-20.
@@Cichlid_Visuals The excess sealant was from when the manufacturer joined the two piece engine; not from resealing the oil pan.
@@avery4528 suabaru has always used alot of sealant when joining the engine components, but we cannot be sure of how much of that silicon actually broke free. regardless, the engine failure was not from silicon plugging anything, he ran the engine low on oil. there hasnt been a single engine failure concretely proven to be caused by RTV.

Stock oil pump always was a garbage that turns oil into a foam. That's the reason
But... Subaru/ Toyota didn't test this car in Nurburgring before to sell them ?....
Misha, I strongly recommend looking into what 900brz and Drivers Paddock on TH-cam have posted about this issue. The RTV is not the main issue as a quick dirty fix at the moment is an oil overfill and syms baffle. Oil cooler is a double edged sword as it keeps oil temps from getting into a danger zone but will be another part that will prevent oil from returning to the pan/sump.
900BRZ showed syms baffle doesn't work. He's had success with a prototype larger oil pan by verus engineering that is still early in the production process.
After owning a Subaru, I can say I wont be going back. The amount of money you need to put into them just to have fun at the track is upsetting.
Toyota should have validated that engine properly like the b58.
Silicon is bad in women and silicon is bad in car engines as well!
lol, how many kms was on it for the bearings to look like that? Fookin hell
I always took my GT86 then BRZ to main dealer and this is the very reason my Gr86 will be going to the dealer for servicing to keep the 10 year warranty
Only Porsche knows how to make flat engines.

Well, yes, they just boOost them a little less...
you mean by using a dry sump?
Porsche has had TONS of its own issues with their boxer engines as well. Boxer engines are wonderful for low CG but a much more complex motor to build due to the layout. Subaru does a fine job for their non-performance oriented motors but when stressed in performance applications, Subaru seems to run out of talent.
Old news. Why not just drop pan, inspect for excess silicon before tracking car initially?
Your on the money with that root cause, way to much silicone used in that reassembly for sure hope it go well from now all the best use Loctite Gasket Sealant very good for Subaru engines Re:
Would an accusump be a good addition in case oil pressure dropped again during a corner?
yes. this has been proven to be the best thing you can do for these engines. it is not expensive and would save 90% of FA24 failures
